12. Turn master gauge carefully until dial
gauge extension is vertical to face of drive
pinion head. At this moment dial
gauge
needle will reach its point of reverse
direction, at which dial gauge must be
read.
Note:
The measured value will always deviate from
the set distance in clockwise direction
(small needle of dial gauge will be between
1 and 2). i. e. when adjusting the dial gauge
with 1 mm preload the value deviating from
1 is added as shim thickness .&.
13. Install the determined shim thickness
S3 between transmission case and final
drive case.
14. Recheck distance after installation of
shims with determined thickness.
A deviation of ? 0.03 mm is permissible.
